Definitions

  • THIS INVENTION relates to a device for cleaning a swimming pool.
  • a device for cleaning a swimming pool which includes
  • wing-like members which have leading and trailing edges and which define a mouth-like opening at leading edges thereof;
  • a draw element which is hingedly attached to the wing-like members for the wing-like members to be pivotal relative to the draw element, about a hinge axis,
  • the device having a specific gravity greater than unity and a centre of gravity and a centre of drag which are located so that a net couple is exerted on the wing-like members when the device falls freely in the water which tends to position the trailing edge of each member above the leading edge of that member.
  • centre of drag is the point through which a resultant force passes equivalent to the drag force that the device experiences as it drops freely in water under the action of gravity, with the wing-like members extending and oriented generally horizontally.
  • the wing-like members may be parallel. They may further be the same length and may be aligned so that the opening is substantially rectangular. Bridging webs may extend between the ends of the wing-like members, to support the wing-like members in their spaced configuration and to define the mouth-like opening. Further bridging webs may be provided intermediate the ends of the wing-like members.
  • the draw element may be secured to the bridging webs at leading ends thereof.
  • the draw element is centrally secured to the bridging webs so that the structure defined by the wing-like members and the bridging webs is symmetrical about a median plane located midway between and parallel to the wing-like members.
  • the hinge axis is close to the leading edges of the wing-like members.
  • the centre of gravity may be caused to be closer to the hinge axis by appropriate shaping of the wing-like and other members.
  • mass members may be provided which are secured either to the wing-like members and/or the bridge members and/or the draw element, to ensure that the centre of gravity is in the desired position.
  • Hinging may be provided by specific hinge members, or by means of hinge regions which have a reduced thickness.
  • Fins may be provided which are carried by the wing-like members on their opposed outer surfaces. Fins may also be carried by the outer bridging webs on their outer sides.
  • the draw element may be forked having prongs extending from a leading bar.
  • the draw element may be attached to a displacing component.
  • the displacing component may be hollow, may be connectable to a hose through which water under pressure is supplied and may have one or more jet nozzles which are directed towards the draw element such that water issuing therefrom causes the component and the draw element to be displaced.
  • the draw element is pivotally attached to the displacing component, by means of a ball-and-socket joint.
  • the wing-like members may be such that, when the device is drawn through the water, with the wing-like members tilted as a result of the net couple exerted by the drag force referred to above, they experience a downwardly directed hydro-dynamic force that tends to assist the weight of the device to cause the device to move downwardly in the water.
  • the Applicant believes that, preferably, the centre of lift should be closer to the hinge axis than the centre of drag.
  • FIG. 1 shows a three dimensional view of a first embodiment of a device for cleaning a swimming pool, in accordance with the invention
  • FIG. 2 shows a sectioned view of the device along line II-II in FIG. 1.
  • FIGS. 3 to 6 shows schematically how the device operates
  • FIG. 7 shows a three-dimensional view of part of a further embodiment of a device in accordance with the invention.
  • FIG. 8 shows a sectioned view of a part of the device in FIG. 7, along line VIII--VIII therein.
  • the device is designated generally by reference numeral 10.
  • the device 10 has two wings 12 which are parallel and spaced apart such that leading edges 14 thereof partly define an opening 16.
  • the wings 12 have an aerofoil profile.
  • the wings 12 are held apart by bridge members 18. There are three bridge members 18, one at either end of the wings and the third midway between the ends of the wings 12.
  • the opening 16 is further defined by leading edges 20 of the end bridge members 18.
  • a foraminous bag 22 is secured to the trailing edges 24 of the wings 12 and end bridge members 18. It will be appreciated that, in use, as described below, debris in the water passes through the opening 16 as the device 10 moves through the water, to be collected in the bag 22.
  • a number of fins 26 are secured to the outer surfaces of the wings 12 and the end bridge members 18. These fins 26 are substantially triangular with their trailing ends being wider.
  • the device 10 further has a draw element 28.
  • the draw element 28 is forked having a leading bar 30 and three prongs 32.
  • the prongs 32 are centrally attached to the leading edges of the bridge members 18 so that the device 10 is substantially symmetrical about a median plane that passes through the middle of the bridge members 18.
  • the prongs 32 Close to their free ends, the prongs 32 have hinge regions 34 which are of a reduced thickness to provide a hinge function. These hinge regions 34 are aligned to define a hinge axis that extends parallel to the leading edges 14 of the wings 12 and midway between them.
  • Lead weights 36 are secured to the prongs 32 close to their hinge regions 34. The purpose of these weights 36 will be explained below.
  • the bar 30 has, at its leading end a ball 38 which is received in a socket 40 in the trailing end of a displacing component 42.
  • the ball 38 and socket 40 define a ball-and-socket joint so that the bar 30 may pivot in two degrees of freedom relative to the component 42 and also swivel.
  • the component 42 is hollow and is engageable at its leading end with a flexible hose 44 through which, in use, water is supplied under pressure.
  • the component 42 further has two jet nozzles 46 which are directed in a downstream direction so that in use a draw force in the direction of arrow 48 is exerted on the component 42 and which is transfered to the draw element 28.
  • the component 42 is in two parts 43 and 45 which are rotatably connected, the part 43 having an internal groove and the part 45 having a complementary circumferential projection.
  • FIG. 3 shows schematically the forces experienced by the device 10 when it is at rest, ie. not being drawn through water 49 in the pool.
  • the device 10 has a specific gravity that is greater than unity so that it sinks in the water 49.
  • the device 10 has centre of gravity 50 which passes through the wings 12 close to the leading edges 14 thereof. If the wings 12 extend horizontally from front-to-back and side-to-side as shown schematically in FIG. 3, and the device 10 is allowed to fall through the water 49 under the action of gravity, the various parts of the device 10 will experience drag forces which have a resultant 52 that passes through a centre of drag 54. As shown in FIG.
  • the centre of drag 54 also passes through the wings 12, with the centre of gravity between it and the hinge axis 34.
  • the device 10 is designed such that the weights 56, the distance of the centre of gravity 50 from the hinge region 34, the drag force 52 and the distance of the centre of drag 54 from the hinge region 34 exerts a net couple on the wings 12 about the hinge axis 34 that is anti-clockwise when seen in FIG. 3, as shown by the arrow 58.
  • the wings 12 would tilt so that their leading edges 14 are below their trailing edges 24.
  • the weights 38 ensure that the centre of gravity 50 is in the desired position.
  • the operation of the device 10 as it moves through the water 49 in the direction of arrow 48 is shown.
  • the device 10 will experience a drag force 52 substantially as it does when at rest and a gravitational force 56 which tilt the wings 12 as described above.
  • the wings 12 have a suitable profile so that a hydro-dynamic force 62 is exerted on the wings 12 which is downwardly directed when the wings 12 are tilted as described, ie. with their trailing edges above their leading edges.
  • This negative-lift force 62 acts through a centre of lift 64 and assists the weights 56 in displacing the device 10 downwardly towards the floor 60.
  • the wings 12 will pivot about the hinge axis 34 to assist the device 10 in passing over the protrusion 68. The forces on the device 10 will thereafter ensure that the device 10 returns to the floor 60 with the desired orientation.
  • FIGS. 7 and 8 a further embodiment of a device in accordance with the invention is shown.
  • This embodiment is similar to that shown in FIGS. 1 and 2 and is similarly referenced.
  • the wings 12 are flat as is clearly seen in FIG. 8, the bag 22 is fast with a frame 72 that has lugs 74 which clip onto pins 76, and the component 42 has a pin 82 with a head 84 that is held in a socket arrangement formed by two parts 78 and 80 at the free end of the bar 30.
  • the parts 78 and 80 clip together.
